Question: What hosted SMTP services are available to outsource your outbound e-mail distribution to increase deliverability? Particularly, if you send a huge number of emails. How should you compare them?

Answer: There’re actually many of them, for example, you could use SMTP.com or sendgrid.com. I have associate relationship with SMTP.com and as far as I understand they’re the only ones who will talk to you before you become their customer there more on the consultant side of business.
